3)Connect a 5V/2A (5V/3A is also available) high-quality power adapter<br>
<div style="padding-left:20px;color:red;font-weight:700;">
a.Remember not to plug in the 12V power adapter, if you plug in the 12V power adapter, it will burn the development board<br>
b.Many unstable phenomena during system power-on and startup are basically caused by power supply problems, so a reliable power adapter is very important
</div>
4)If you want to view the output information of the system through the debug serial port, please use the USB to TTL module and DuPont cable to connect the development board to the computer. For the connection method of the serial port, please refer to the section on the use of the debug serial port<br>
5)Then turn on the switch of the power adapter, if everything is normal, the serial terminal can see the output log of the system startup at this time<br>
<br>

=== '''How to use the debug serial port''' ===

==== '''Debug serial port connection instructions''' ====
1)First, you need to prepare a USB to TTL module. This module can be bought in Orange Pi Store. If there are other similar USB to TTL modules, you can also insert the USB port of the USB to TTL module into the USB of the computer Interface
<div >[[File:Orange-pi-one-img9.png|600px]]</div>
2)The corresponding relationship between the debug serial port GND, TX and RX pins of the development board is shown in the figure below
<div >[[File:Orange-pi-r1-plus-lts-img18.png|600px]]</div>
3)The GND, TX and RX pins of the USB to TTL module need to be connected to the debug serial port of the development board through a Dupont cable<br>
<div style="padding-left:20px">
a. Connect the GND of the USB to TTL module to the GND of the development board<br>
b. Connect the RX of the USB to TTL module to the TX of the development board<br>
c. Connect the TX of the USB to TTL module to the RX of the development board
</div>
<br>
4)The schematic diagram of connecting the USB to TTL module to the computer and the Orange Pi development board is shown below
<div >[[File:Orange-pi-3lts-ttlmodule2.png|600px]]</div>
<br>
5)If you are using a CP2102 USB to TTL module, under the condition of a baud rate of 1.500000, some systems may encounter garbled or unusable problems. The specific test situation is as follows
{| class="wikitable" style="width:800px;"

<br>

====  '''How to use the debugging serial port on Ubuntu platform''' ====
1)If the USB to TTL module is connected normally, you can see the corresponding device node name under /dev of the Ubuntu PC, remember this node name, it will be used when setting the serial port software later
<div style="background:#f1f1f1;border:1px solid #000">
test@test:~$ '''ls /dev/ttyUSB*'''<br>
/dev/ttyUSB0
</div>
<br>
2)There are many serial debugging tools that can be used under linux, such as putty, minicom, etc. The following demonstrates how to use putty<br>
<br>
3)First install putty on the Ubuntu PC
<div style="background:#f1f1f1;border:1px solid #000">
test@test:~$ '''sudo apt update'''<br>
test@test:~$ '''sudo apt -y install putty'''
</div>
<br>
4)Then run putty, remember to add sudo permissions
<div style="background:#f1f1f1;border:1px solid #000">
test@test:~$ '''sudo putty'''
</div>
<br>
5)After executing the putty command, the following interface will pop up

<br>
6)First select the setting interface of the serial port
<div >[[File:Orange-pi-3lts-putty1.png|600px]]</div>
7)Then set the parameters of the serial port<br>
<div>
a. Set the Serial line to connect to to /dev/ttyUSB0 (modify to the corresponding node name, generally /dev/ttyUSB0)<br>
b. Set Speed (baud) to 1500000 (baud rate of the serial port)<br>
c. Set Flow control to None
</div>
<div >[[File:Orange-pi-r1-plus-lts-img19.png|600px]]</div>
8)After setting the serial port setting interface, return to the Session interface
<div style="padding-left:20px;">
